Have you ever opened a carton of organic milk only to be hit with an unpleasant odor?
It can be a disconcerting experience that leaves you wondering, “Why does organic milk stink?”
In this article, we’ll explore the reasons behind this smell and offer tips on how to determine whether your organic milk is still safe to drink.
Key Takeaways
- Organic milk contains higher levels of BCM-7, which can contribute to its distinct odor.
- Factors such as cow diet and processing methods can also affect the smell of organic milk.
- Proper storage and handling can help prevent organic milk from spoiling and developing an unpleasant smell.
Understanding Organic Milk
Organic milk is a type of milk that comes from cows that are raised without the use of antibiotics or hormones. The cows are also fed with organic feed, which means that they are not exposed to any synthetic pesticides or fertilizers.
Organic milk is often considered to be healthier than regular milk because it contains fewer harmful chemicals and is richer in nutrients.
One of the reasons why organic milk smells bad is because it is not pasteurized at high temperatures like regular milk.
Pasteurization is a process that kills harmful bacteria in milk by heating it to a high temperature. However, this process also destroys some of the beneficial nutrients in milk.
Organic milk is only pasteurized at a lower temperature, which means that some of the bacteria in the milk are not killed. This can cause the milk to spoil more quickly and produce a sour smell.
Another reason why organic milk smells bad is because it contains more fat than regular milk.
Fat is an important component of milk, but it can also go rancid over time. When fat goes rancid, it produces a sour smell that can be unpleasant.
Organic milk is often higher in fat than regular milk because the cows are allowed to graze on grass, which is a natural source of fat.
Despite its strong odor, organic milk is still safe to drink as long as it has not gone bad. In fact, some people prefer the taste of organic milk because it is creamier and richer than regular milk.
If you want to try organic milk, it is important to buy it from a reputable source and make sure that it is within its expiration date.

The Science Behind the Smell
Organic milk is known for its distinctive smell, which can be off-putting to some people.
The smell is caused by a compound called beta-casomorphin-7 (BCM-7), which is formed when cows digest the protein in grass. BCM-7 is found in both organic and non-organic milk, but it is present in higher levels in organic milk.
To understand why organic milk smells different, it’s important to understand the process of digestion in cows. When cows eat grass, the protein in the grass is broken down into peptides, which are then absorbed into the bloodstream.
These peptides can then cross the blood-brain barrier and bind to opioid receptors in the brain, producing a calming effect on the cow.
However, some of these peptides are further broken down into smaller peptides, including BCM-7. This peptide is not broken down by the cow’s digestive system and is therefore present in the milk that the cow produces.
Health Implications of the Smell
While the smell of organic milk may be off-putting to some people, there is no evidence to suggest that it is harmful to human health. In fact, some studies have suggested that BCM-7 may have beneficial effects on the immune system and may even have anti-cancer properties.
However, more research is needed to fully understand the health implications of BCM-7. Some people may also be intolerant to BCM-7 or other peptides found in milk, which can cause digestive issues such as bloating, gas, and diarrhea.
It’s also worth noting that the smell of organic milk may vary depending on a number of factors, including the cow’s diet, the season, and the processing method used. Ultra-pasteurized organic milk may have a different smell than minimally processed organic milk, for example.
Overall, the science behind the smell of organic milk is complex and not completely understood. While some people may find the smell off-putting, there is no evidence to suggest that it is harmful to human health.
THREE Additional Factors Affecting the Smell of Organic Milk
1. Storage Conditions
The storage conditions of organic milk can affect its smell. Organic milk should be stored at a temperature between 33°F and 40°F to maintain its quality. If organic milk is stored at a higher temperature, it can develop a sour smell. On the other hand, if it is stored at a lower temperature, it can develop a stale smell.
Organic milk should also be stored in a clean and dry environment. Any contamination in the storage area can affect the quality of the milk and cause it to develop an unpleasant smell.
2. Expiry Date
The expiry date of organic milk can also affect its smell. Organic milk that is past its expiry date can develop a sour or rancid smell. It is important to check the expiry date of organic milk before purchasing it and to consume it before the expiry date.
3. Packaging Material
The packaging material of organic milk can also affect its smell. Organic milk is typically packaged in cartons or bottles made of paper or plastic. If the packaging material is not of good quality, it can affect the quality of the milk and cause it to develop a stale or off smell.
Organic milk should be stored in its original packaging until it is consumed. Once the packaging is opened, the milk should be consumed within a few days to maintain its quality.
| Factors | Effect on Smell |
|---|---|
| Storage Conditions | Can develop a sour or stale smell if stored improperly |
| Expiry Date | Can develop a sour or rancid smell if past expiry date |
| Packaging Material | Poor quality packaging can cause a stale or off smell |
How to Properly Store Organic Milk
Organic milk can last longer than regular milk due to the process of ultrahigh temperature (UHT) treatment.
However, improper storage can lead to spoilage and a bad smell. Here are some tips on how to properly store organic milk to ensure its freshness and taste.
| Tips for Storing Organic Milk | |
|---|---|
| Keep it Cold | Organic milk should be stored in the refrigerator at a temperature between 33 and 40 degrees Fahrenheit. This will help prevent the growth of bacteria that can cause spoilage. |
| Avoid Exposure to Light | Light can cause organic milk to spoil faster, so it’s best to store it in a dark place. Consider using a container that is opaque or wrapping the milk in a dark cloth or paper towel. |
| Keep it in the Original Container | Organic milk should be kept in its original container to maintain its freshness. Avoid transferring it to another container as this can expose the milk to air and bacteria. |
| Use it Before the Expiration Date | Organic milk has a longer shelf life than regular milk, but it still has an expiration date. Be sure to use it before the expiration date to ensure its freshness and taste. |
| Do Not Freeze Organic Milk | Freezing organic milk can alter its texture and taste. It’s best to avoid freezing it and consume it before the expiration date. |
Following these tips will help ensure that organic milk stays fresh and does not develop a bad smell. If organic milk has a sour smell, it may be a sign that it has spoiled and should be discarded.
